Stereo to 5.1 upmix tutor

would love a tutor on using the surround plugins to get a better surround sound mix ie with the dts upmix and some of the other waves surround plugins

Hello.
I am a big fan of surround sound but I don’t know much about Music editing. I own Sound Forge Pro and I’m able to use plug-ins for easy editing of wav-files. I would like to use the DTS Neural UpMix Plugin or the UM225/226 Plugin to convert stereo-files in surround files, but this doesn’t seem to work with Sound Forge Pro. Is there a simple possibility to use these plugins simply to convert Stereo to Surround? Have you found a way to use surround plugins? Which software do you use?
